Abstract: A system and method for effectively and reliably terminating a voice call in any burst within a multi-burst superframe. A transmitting unit generates a termination burst upon detecting a dekey event. The termination burst inc ludes a data synchronization pattern, a slot type field indicating an end of a call, and an information field surrounding the data synchronization patte rn and the slot type field. The information field is encoded from a predeter mined voice encoder frame unique to the termination burst. Once all buffered voice information is transmitted, the termination burst is transmitted prio r to the end of the multi-burst superframe. A base station or other receivin g unit monitors the incoming signal. Upon detecting the data synchronization pattern, the receiving unit decodes the slot type field and the information field. The receiving unit determines whether the decoded slot type field is indicative of the end of a call, and whether a specific portion of the deco ded information field matches the predetermined voice encoder frame. If both are true, the receiving unit terminates the call.

The information field is encoded from a predetermined voice encoder frame unique to the termination burst. Once all buffered voice information is transmitted, the termination burst is transmitted prior to the end of the multi-burst superframe. A base station or other receiving unit monitors the incoming signal. Upon detecting the data synchronization pattern, the receiving unit decodes the slot type field and the information field. The receiving unit determines whether the decoded slot type field is indicative of the end of a call, and whether a specific portion of the decoded information field matches the predetermined voice encoder frame.

Abstract: A receiver (350) compatible with both wide channel constant envelope 4 level FSK FM modulation and narrow channel .pi./4 differential QPSK linear modulation allows compatible interaction between modified constant envelope and non-constant envelope transmitters (300). All Nyquist filtering occurs in the transmitters (300), and none in the receiver (350).

Abstract: A received synchronization pattern is compared against first and second know n synchronization patterns. If the received pattern is substantially similar t o the first known pattern, the payload is processed as voice; and if the received pattern is substantially similar to the second known pattern, the payload is processed as non-voice. Alternatively, a target synchronization pattern dependent on an operating mode is selected. The received pattern is compared against the target pattern. If the received pattern is substantiall y similar to the target pattern, the payload is processed; otherwise, the burs t is discarded. In yet another alternative, the received pattern is compared against first and second known synchronization patterns having a common length. If the received pattern is substantially similar to the first known pattern, a first operating mode is selected, and if the received pattern is substantially similar to the second known pattern, a second operating mode i s selected.

Abstract: In a wireless communication system with an air interface comprising a plurality of bursts, a plurality of bursts is defined. Each burst comprises a field (300) embedded within the burst. The field (300) is one of a synchronization field (300') and a signaling field (300''). When the field (300) is a synchronization field (300'), a position of at least one subsequent burst comprising the signaling field (300'') is defined, and a position of at least one subsequent burst comprising the synchronization field (300') is defined.

Abstract: The method involves receiving a signal frame (207-209) from each of several base stations (202-204) for generating several signal frames. Each signal frame comprises a group of code words which include a priority code word to generate several priority codewords. Each priority codeword is located at a certain position of a signal frame and has an appropriate measure of signal quality for generating several measures of signal quality. It is determined whether the measures of signal quality correspond to the priority code words. An additional measure of signal quality is determined for each priority code words for generating several additional measures of signal quality. A priority code word is selected which is based on a comparison (206) with the additional measures of signal quality for generating a selected code word.

Abstract: SECURE COMMUNICATION SYSTEM Disclosed is a synchronous secure communication system (Figure 1) wherein an information signal is encrypted in an encryption means (208). The encrypted signal is compressed (210) to allow the insertion of a pseudo-random synchronization signal (212), and the combined signals are transmitted (220). At the receiver, the pseudo-random synchronization signal is extracted (232) and used to synchronize the receiver to the incoming data stream thereby improving receiver sensitivity and range.

Abstract translation: 一种用于在多突发超帧内的任何突发中有效且可靠地终止语音呼叫的系统和方法。 发送单元在检测到密钥事件时产生终止突发。 终止突发包括数据同步模式，指示呼叫结束的时隙类型字段以及围绕数据同步模式和时隙类型字段的信息字段。 信息字段是从终止突发所特有的预定话音编码器帧编码的。 一旦发送了所有缓冲的语音信息，终止突发就在多突发超帧结束之前被发送。 基站或其他接收单元监视输入信号。 在检测到数据同步模式时，接收单元对时隙类型字段和信息字段进行解码。 接收单元确定解码时隙类型字段是否指示呼叫结束，以及解码信息字段的特定部分是否匹配预定语音编码器帧。 如果两者均为真，则接收单元终止该呼叫。
